The Causses du Quercy are a lived-in landscape of limestone plateaux, villages, pasture, woodland and river valleys in the Lot, in Occitanie. The regional nature park covers about 186,000 hectares and 95 communes. There is no single entrance or opening time for the whole territory. Individual attractions, private land and protected sites have their own access rules.
For a first visit, concentrate on the Phosphatières du Cloup d’Aural near Bach, in the southern part of the park. It brings several strands of the landscape together in one manageable outing. The ground beneath the plateau is riddled with cavities formed by water acting on limestone. At the surface, dry grasslands alternate with scrub and woods; the greener depths of the phosphatière make the contrast especially striking.
The fossil story belongs to a network of ancient cavities across the Quercy. Animals and plants became preserved in their sediment, leaving an exceptional record of changing life and environments over roughly 30 million years. The park has held UNESCO Global Geopark status since 2017. The geosite offers a compact introduction to that much larger territory.
Living vegetation tells a different story. A botanical study of Cloup d’Aural describes thin, stony soils around the hollow and cooler, damper conditions within it. Water-retaining clay deposits support lush growth below. The lush vegetation belongs to today’s cool microclimate; the fossils describe vanished environments. Ask the guide to help you read the changes in light and vegetation as you descend. Enhance your adventure: download the Snappit app to identify the local species you encounter.
The park was created in 1999, but the human story at Cloup d’Aural is much older. In the late nineteenth century, phosphate extraction emptied ancient deposits and brought fossils to light. What was once worked as a mineral resource became a scientific archive. The Geological National Nature Reserve of the Lot, created in 2015, now protects scattered sites, including phosphatières. Its protected parcels are not all public visitor attractions: Cloup d’Aural’s managed route gives you a properly interpreted way into this landscape.
Build your visit around the guided descent, then choose the outdoor interpretation and exhibition at your own pace. Families can add a discovery game. Use the visit to connect three questions: how the hollow formed, why people mined it, and why its living vegetation differs from the plateau.
Individual visits generally run from early April to early November, with selected openings during the Christmas and winter school holidays. Departure times change through the year. Choose a dated slot on the operator’s calendar rather than treating ticket-office hours as tour times.
The descent has about 140 steps down and the same climb back. It is not a step-free route. The operator describes the surface paths and exhibition as accessible to wheelchairs and pushchairs; discuss the ground surface and your particular needs before booking.

The operator gives 300 m for the return guided route and a 20 m level change. The short distance is deceptive: this is a visit with explanations and a stair descent, followed by a climb out. Keep your hands free for the rail and let the guide set the pace. Allow about one hour for the tour.
About 140 steps lead down, then back up. A handrail and landings help, but this section cannot be done in a wheelchair or pushchair.
Choose the panels that interest you most: phosphate, geological time, plants, palaeontology or animals of the past. The operator gives 30 minutes to 2 hours for this self-guided part, depending on reading time. It can go before or after the descent; agree the order at reception, especially for a late tour.
The operator describes the surface paths as suitable for wheelchairs and pushchairs. They include crushed-limestone surfacing; check firmness, gradients and assistance needs directly.
Check in at least 15 minutes before your reserved tour. Fit the one-hour guided visit, one discovery game and a focused exhibition visit around that booking. Take a break before the climb if needed and allowed by the guide. If concentration is fading afterwards, leave the remaining panels for another visit rather than adding an unplanned walk.
If the stairs do not suit someone in your party, discuss the surface interpretation and exhibition with staff before buying tickets. Ask what can be offered, how the group can reunite and whether the standard ticket applies. The surface visit offers its own perspective on the site; confirm the available ticket options directly.
Ask for the activity sheet at reception. The Jeu des Animaux du Passé takes about 30 minutes; Sur la piste du Cadurcothère is listed at 30–60 minutes. Picking one gives younger visitors a clear mission without turning the whole afternoon into an endurance test. The operator recommends the visit from around age five.
Allow 30–60 minutes for the self-guided exhibition. Before you enter, invite each person to choose one question from the tour: what miners wanted, what a fossil can reveal, or how a landscape changes. Compare the answers afterwards. There is no need to read every display to come away with a coherent story.
From permitted stopping points, make a pair of pictures: the surface landscape and the vegetation below. Try to show differences in light and plant cover rather than collecting a specimen. Leave room for other visitors and put the camera away while using the stairs.
This is an open-air chasm, not a weatherproof cave attraction. Take waterproofs and grippy shoes for light rain. In severe weather, follow the operator’s cancellation advice. The exhibition is useful shelter during an authorised visit, but do not assume it stays open independently if tours are cancelled.
A 2017 botanical study records this fern at Cloup d’Aural under its former name, Phyllitis scolopendrium. Ask the guide to point it out from the route; the record is not a guarantee that a particular plant will be visible on your visit.
Male fern is also named in the site’s 2017 botanical study. Use it as a reason to look closely at the varied fern growth, rather than treating every green frond as the same species. Leave identification to the guide where details are unclear.
The park runs an observatory for this protected lizard, whose habitat is threatened by loss and overgrowth. This is a wider-park species, not a promised sighting at Cloup d’Aural. If you happen to see one, watch without approaching its refuge or moving stones.
The remarkable long record comes from many Quercy phosphatières considered together. It should not be read as a promise that one hole contains every period or every animal. Ask which part of that larger story the guide is describing at each stop.
The park works with farmers and landowners to bring grazing back to overgrown areas. Maintaining open habitat supports its characteristic biodiversity and is also part of reducing fire risk. When you see grazed ground, gates or stock fencing elsewhere in the park, you are looking at a working conservation landscape.
Use a mild day for the outside interpretation, but expect the bottom to feel chilly. Shoulder-season opening can be split or restricted to a few departures, so organise lunch and arrival around the calendar.
The cool hollow can be appealing, but part of the visit remains in the open. Carry water and sun protection, avoid packing the hottest part of the day with extra walking, and check official heat and fire restrictions before exploring beyond the site.
Some holiday dates have individual visits; this is not a promise of daily winter opening. Confirm the date and departure directly, take warm clothing and leave plenty of daylight for your journey afterwards.
The site lists toilets, a shop, a shaded picnic area and parking. Parking is free. Bring your own food: drinks are sold, but the operator does not offer meals. The picnic area is inside the managed site and may be unavailable during a midday closure.
Use Phosphatières du Cloup d’Aural, 1546 Route des Phosphatières, 46230 Bach. The car park is reached from the D19 near reception. Do not navigate to the Maison du Parc at Labastide-Murat for this visit; it is a different destination.
Cahors is the railway gateway listed by the tourism office, about 30 km from the site. Arrange onward and return transport to Bach before choosing a tour time. For local advice, call the site on +33 5 65 20 06 72. Do not rely on finding an immediate connection after a late visit.
Walking distance alone does not measure the effort of climbing back out. If you tire easily, have balance difficulties or travel with a baby, talk through the route with staff first. Pushchairs must remain above the steps. Ask about accessible toilets and the exact approach from the car park as well as the paths; the general surface-access statement does not answer every individual need.
The published 2026 prices are €13 for a standard adult, €12 at the reduced rate, €9 for ages 5–14, €8 for disabled visitors aged 5–17, and free for ages 0–4. Reduced-rate eligibility includes ages 15–17, disability and jobseekers; check the conditions when booking. The entry ticket covers the guided visit, interpretation paths and exhibition.
Reserve a dated departure through the official ticket page or contact the site. Its booking terms say prepaid tickets are not refunded for customer cancellation, though transfer to a later slot for the same service may be possible. Read the current terms before payment, particularly if your plans depend on weather or mobility.
Each card links to a full Explore page with photos, traits, and fun facts.

Start with the big picture, then zoom in to explore individual wildlife observations around this place.
Reserve a tour before making the journey and arrive at least 15 minutes before its departure.
Wear shoes with a good grip and bring a warm layer; rain can make the steps slippery.
If you choose the final guided tour, do the self-guided sections first and check when the gate closes.
Leave fossils, minerals, plants and mosses where they are. A discovery game is not permission to collect.
Bring a picnic if you want lunch here, but check that the site remains open over midday.
Keep dogs on a lead and keep children with you on the descent.
